AutoMeter 3640 Details

One of the single most important factors in determining how your engine performs (and how long it performs between rebuilds) is proper oil temperature during operation. Knowing your exact temp allows you to make sure you've got the proper oil weight and cooling capacity. Using AutoMeter's advanced 1/8" NPT two wire temperature transducer, you can be assured of the most accurate possible readings of the life blood of your engine. The advanced Digital Stepper Motor Drive keeps needle movement smooth and precise. A direct plug in wiring harness is included for ease of installation.
